Alternating seal pattern for retroreflective trim



The present invention is a new and ornamental design for an alternatingseal pattern applied to a strip of retroreflective material, which stripof retroreflective material is referred to herein as retroreflectivetrim. The seal pattern can be an artifact of localized melting (e.g. byknown radio frequency welding, ultrasonic welding, or hot can processes)two components of the retroreflective material together—aretroreflective sheeting and a separate seal film—to form sealed cellsthat protect minute retroreflective elements on the retroreflectivesheeting.

FIG. 1 is a perspective view of an alternating seal pattern forretroreflective trim, showing our new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a side view thereof; and,

FIG. 5 is an end view thereof.

The breakaway lines at the end of the depicted retroreflective trimindicate that the length of the trim is not limited, it being understoodthat the ornamental seal pattern can repeat along such length.

The ornamental design for an alternating seal pattern forretroreflective trim, as shown and described.
